JRebel

What do you like best?

By removing the time needed for redeployment of the Java applications JRebel decreased the development time, increased the developers' focus on the task at hand, increased the productivity and therefore decreased the time to market of the new features. On top of all, it saves company money and you can even use a calculator in their User Interface to quantify it.

For example: a team of 2 Java developers with 4 redeployments per hour, 2 minutes each, JRebel will reduce the time wasted that costs $8000 per year, with a $25 cost per hour for a developer.

What do you dislike?

The User Interface for managing licenses, reports, users is not user friendly enough. I had issues in the past while managing/allocating the licenses; we use a combination of dedicated and floating and it is not that straightforward to manage these in the UI.

Recommendations to others considering the product:

Any Java developer should use JRebel. The time saved for redeployments translates into time spent actually working on the task and delivering it faster. It will make developers happier, project managers happier and the project goes to production sooner.

What problems are you solving with the product? What benefits have you realized?

We have shorten the release cycle in an Agile Scrum model to less than 2 weeks, given that now we are able to do intermediate releases for small features during the sprint itself. Our customers are happier, the development team has more focus and a better sense of completeness.
